Definitions
- the present invention relates to an elastic connecting rod for surgical treatment of the spine, the rod having different degrees of stiffness along its longitudinal axis according to the preamble of claim 1 .
- Elastic connecting rods are typically used in conjunction with pedicle screws for the dynamic stabilization of the spine. If such a rod can be provided with a section of higher stiffness, the possible indications can be substantially extended. Thus, a section of higher stiffness may be used for the fusion of vertebral bodies while a section of lower stiffness may be used for the elastic connection of a neighboring vertebral body.
- the invention according to patent application US 2008/0319486 discloses a connecting element having a variable stiffness along its longitudinal axis.
- the variable stiffness is limited to the sections between two anchoring elements and provides a different response to pressure only.
- the invention according to EP 2 113 216 also provides different degrees of stiffness.
- the connection of the different materials is either achieved by interpenetration or by a butt joint.
- the material differences are limited to differences in hardness and in bending flexibility. Differences in longitudinal or transversal stiffness are not disclosed.
- the butt joints are designed for normal stresses exclusively.
- the invention according to patent application WO 97/32533 provides a varying stiffness due to a varying external diameter, thereby making the rod more difficult to anchor.
- the invention according to patent application US 2008/0306536 aims to achieve a variable stiffness between vertebral bodies by connecting the connecting element to the bone screw with variable stiffness. This solution is space-consuming and may have unfavorable consequences for the patient.
- the invention according to patent application US 2005/0203513 also provides different degrees of stiffness in that for one part, the core inside a cylindrical wall varies or, for the other part, the stiffness of a connecting element is locally reduced by material removal.
- this entails the difficulty of anchoring a core by means of a wall of a different kind, and on the other hand, the difficulty of sections of predetermined length, which in the case of multisegment treatments involves significant logistic complexity.
- the invention according to patent application US 2007/0129729 also provides a stiff and an elastic rod portion whose connection is interpenetrating and is supported by a cable.
- the invention according to patent application US 2006/0041259 provides a variable stiffness along its rod axis.
- the variation is achieved by a helical slot (or spiral slot) reflecting the mechanical principle of a spiral spring.
- the spring may also be filled with a core and such core may be secured to the spring by welding or bonding.
- the variation may further be achieved by assembling rods of different properties one behind the other.
- the patent application does not disclose any method of sequentially connecting one rod to the other. Nor does it disclose how the anchorage of the rod in a bone screw would interface with such a connection site.
- connections are butt joints, at least peripherally, and thus extend in a plane parallel to the clamping plane in the screw head.
- rod segments having different degrees of stiffness are interconnected in a plane that is oblique to the longitudinal rod axis.
- the connection may be achieved by bonding or welding or by a combination of both.
- heating techniques e.g. plates or mirrors
- motion techniques e.g. vibration or ultrasonic welding
- a combination of both may be contemplated.
- the plastic material may be a polycarbonate urethane.
- the present invention discloses a connection of different rods along an inclined plane, in order to not only have normal loads across the connection site, i.e. perpendicular to the connection plane, but also shear loads.
- the present invention discloses rods with plain sections and connection areas extending over the entire cross section. The inclination angle of the inclined plane is determined in order to avoid an anchorage which clamps from two opposite sides across the connection plane.
- a connecting plane coincides with a clamping plane and the connection, besides normal stresses, is also ensured by more suitable shear stresses.
- FIG. 1 a a point-symmetrical rod having sections of different degrees of stiffness connected via an oblique plane;
- FIG. 1 b a rod having an arbitrary cross-section (e.g. with two plane-parallel sides) and sections of different degrees of stiffness connected via an oblique plane;
- FIGS. 2 a and 2 b the reaction forces for a rod connected by a butt-joint
- FIGS. 3 a and 3 b the reaction forces for an oblique connection according to the invention and the angle ⁇ of the connecting plane;
- FIG. 4 clamping ridges on a butt joint
- FIG. 5 clamping ridges on an oblique connection.
- FIG. 1 a shows a left 1 and a right 2 segment of a rod 41 having a point-symmetrical cross-section 4 and the oblique weld seam 3 connecting them.
- FIG. 1 b shows a left 1 and a right 2 segment of a rod 42 having an arbitrary cross-section 5 , e.g. with two plane-parallel sides, and the oblique weld seam 3 connecting them.
- FIGS. 2 a and 2 b show an upper 6 and a lower 7 segment of a rod 44 connected by a butt joint 8 according to the prior art.
- arrow 9 represents the external force
- arrow 10 the reaction force in a sectional view.
- the reaction force exclusively consists of a normal force according to arrow 10 .
- FIGS. 3 a and 3 b show an upper 11 and a lower 12 segment of rod 46 interconnected by an oblique joint 13 .
- arrow 14 represents the external force and arrow 15 the reaction forces in a sectional view.
- the reaction forces consist of a normal force 15 a and of a shear force 15 b .
- the angle ⁇ denotes the angle between the plane of the joint 13 and the longitudinal axis 47 of rod 46 , or, as illustrated, the side face of rod 46 .
- FIG. 4 shows an upper 6 and a lower 7 segment of a rod 46 connected by a butt joint 8 . If clamping ridges 18 apply on the connecting plane, they will apply a load to the weld seam of joint 8 from both sides.
- FIG. 5 shows an upper 11 and a lower 12 segment of an obliquely connected rod. Clamping ridges 18 apply on one side of the weld seam 13 at the most.
- a clamping device comprises ridges 18 located in one and the same clamping plane and if these ridges apply in a connecting plane 8 that is orthogonal to the rod axis, they will penetrate into the connecting plane from both clamping sides. In the case of a bonded joint or a weld seam, a critical splitting force may result.
- a clamping device comprises ridges 18 located in one and the same clamping plane and if these ridges apply to an oblique connecting plane 13 , only one ridge 18 may apply a load to the connection on one clamping side, and no force is exerted on other sections of the connection plane 13 . Moreover, the clamping does not act in the oblique connecting plane and thus has no direct splitting or cleaving effect either.
- connection method allows connecting rod segments with large differences in longitudinal or transversal stiffness.
- the rod segments have to be dry.
- these have to be rehydrated after their connection and delivered in a preferably saturated condition.
